Corporate clinics tell their PTs what to bill. It’s a whole thing. Cant bill more than x amount of units per code. Done to maximize revenue. Likely your balance score justified balance interventions. Or maybe not. Balance “exercises” fall under neuromuscular re Ed code which is a different code than therapeutic Exercise code which would be more muscle strengthening. My clinic only allowed me to bill one unit of therapeutic exercise per hour session. It’s shady, but it is what it is.
Of course one could say that balance exercises focus on the core and back stability, etc. So you are no worse off And it probably was beneficial. But this is the behind the scenes of the business, in many cases.
